<p>Hi!</p>
<p>This looks like it should be solvable using one or more keyboard
macros [1].</p>
<p>Here is one I just created:</p>
<pre>~~~~
(fset 'experiment-to-json-macro
(kmacro-lambda-form [?\M-m ?l ?a ?b ?e ?l ?: ?\S- M-right ?\} ?\M-m ?\{ ?v ?a ?l ?u ?e ?: ? ?\" ?\" ?, ? ?\C-s ?\" return left M-S-right ?\M-w M-left M-left M-left M-S-right ?\C-y M-S-left ?\M-x ?d ?o ?w ?- ?r ?e ?g return M-S-right ?\M-% ? return ?- return ?! home down] 0 "%d"))
~~~~
</pre>
<p>> This inserts some Lisp code that, when executed later, will
define the same macro with the same definition it has now. -- [2]<br>
</p>
<p>(1) Basically you do the line manipulation for one line, (2)
while always keeping in mind to only use movements of the cursor,
which are generally applicable to all lines (4) move the cursor to
the next line (5) and finish the macro. (6) Then you can use that
macro on multiple lines by using the universal argument as
follows:</p>
<p>C-u <enter num of lines here> C-x e</p>
<p>Which runs the last macro you number of lines times. It is
important, that you move the pointer to the next line at the end
of your macro, so that the macro can be run over and over again,
moving to the next line by itself, not requiring you to move to
the next line after each macro run.</p>
<p>At the start of the macro I used M-m to go to the first character
in the line. I could have started recording the macro already with
the pointer at that place and not press M-m, but then whatever I
store would be less general, as it would depend on the pointer
position, when the macro is invoked.</p>
<p>Hope this helps!</p>

<pre class="moz-quote-pre" wrap="">Hello everyone,
the other day I've failed to solve a small task consisting of text
search and replace in a file. I'm asking for an opinion on how could I
have solved this using Emacs. This could have been an interesting
question during the meetup :-)
Task: you have a text file of about 1000 lines in this format:
---snip-snip-snip-snip-snip---
[
"ONLY CAPITAL CASE",
"ALSO THIS ONE",
"HANDS ARE TYPING",
"NO WEIRD CHARS, ONLY LETTERS, NUMBERS AND PUNCTUATION",
...
]
---snip-snip-snip-snip-snip---
You want to transform it into a JSON where each label goes into a `label`
field, plus a `value` field with a "slug" of the label. A "slug" is a
conversion of some text replacing puntuation and whitespaces with
hyphens, example follows:
---snip-snip-snip-snip-snip---
[
{ value: "only-capital-case", label: "ONLY CAPITAL CASE"},
{ value: "also-this-one", label: "ALSO THIS ONE"},
{ value: "hands-are-typing", label: "HANDS ARE TYPING"},
{ value: "only-letters-numbers-and-punctuation", label: "ONLY LETTERS, NUMBERS
AND PUNCTUATION"},
...
]
---snip-snip-snip-snip-snip---
I've tried either using the `multiple-cursors` package, I've tried
learning my first macro, I've tried with `M-x query-replace-regexp`. All
my attempts have failed. I could not learn how to use these by reading
the documentation.
My solution: ended up with 10 lines of Python :-/
So, who's up for some Emacs-fu? :-) Thanks!
p.s. I had to set Emacs in `so-long` mode because it struggled with a
1000 lines file (I'm on Emacs native-comp).
Best,
